The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be further purified before it can be refined ...
The purification of bauxite containing silica as the main impurity is done by Serpeck's process. The powdered ore is mixed with coke and heated to about 2073 K in an atmosphere of nitrogen. The powdered ore is mixed with coke and heated to about 2073 K in an atmosphere of nitrogen.

Solution Verified by Toppr Finely powdered bauxite (Al 2O 3) is heated with coke and N 2 to 2000 K. Alumina forms aluminium nitride and silica is reduced to Si which is volatile. The hydrolysis of aluminium nitride gives aluminium hydroxide which on heating gives pure alumina. Al 2O 3⋅2H 2O+N 2+3C 2000K 2AlN+3CO↑+2H 2O SiO 2+2C→Si↑+2CO↑
Highly reactive metals with lower reduction potentials than hydrogen are not obtained by electrolysis of aqueous solutions of their salts since their cations cannot be reduced at cathode in presence of water. Of the above metals, Magnesium is the only metal which has reduction potential less than that of Hydrogen. Hence, Option "B" is the correct answer.

Nitric oxide does not form as a byproduct in Serpek's process. Hence, the option (D) is incorrect. Note: We have to know that the Serpek's process is mainly used for the purification of bauxite which contains high amounts of aluminium and silica as impurity. And it is a reaction of bauxite with cock and there is a formation of aluminium ...

Serpeck's process Bayer's method and Hall's method is used for the red bauxite which contains F e 2 O 3 and silicates as impurities. Serpeck's method is used for the white bauxite which containes silica as impurities.
Serpeck's process is the process of converting bauxite into aluminum nitride. This process is generally used when silica is present in the bauxite ore. Therefore, Hall's process, Baeyer's process and Serpeck's process are the various processes used for the purification of bauxite. Hence, options A,B and C are correct. Separation ...
(A) Red bauxite contains the impurities of iron oxides SiO 2 and TiO 2. (B) Red bauxite is purified by Hall's and Serpeck's process (C) HallHeroult process is used for the electrolytic reduction of molten alumina dissolved in molten cryolite. (D) In electrolytic reduction of alumina fluorine gas is liberated at anode as by product.
